You can’t pop the question without an engagement ring. And you can’t buy a ring without knowing her ring size. Of course, obtaining that information isn’t always easy. Here are five tips for covertly determining what size ring to buy.Ask one of her friends
Get in touch with a friend or family member of your significant other. They may have bought her a ring as a gift before, or the topic of ring size could have popped up in conversation. If they don’t know then you can always recruit them as an accomplice. Have someone take her “window shopping” for an engagement ring and get her to see what her ring size is for “fun”.
”Borrow” a ring
If you can get your hands on a ring that your girlfriend wears you can take it to a jeweler and get it measured. However, in order to get an accurate measurement you’ll need to be sure that the ring actually fits her properly and it is worn on the correct finger (left ring finger), as all fingers are different sizes. If she does not wear a ring on that finger you can settle for an estimated measurement for another finger, but beware the ring will most likely need to be re-sized.
Create a replica
Say you are unable to take her ring to a jeweler without her noticing it’s missing, there are several ways you can estimate the size without taking the ring out of the home. For one, you can try the ring on yourself and mark on your finger where it falls. Then you can go to a jeweler and have them find the size that falls in the same place. Also, you can make an impression of her ring in a bar of soap or clay and take it in for measurement. One last way is to trace the inside of her ring with a pencil and have a jeweler match the size.
In the middle of the night
While your girlfriend blissfully slumbers, unaware of what you have planned you can wrap a piece of paper or string around her ring finger and mark the size that way. If you bring this in to a jeweler they can help you to find a measurement. Just make sure she’s not a light sleeper.
A ring is easier to re-size if it is too big, and most jewelers offer free resizing. Just note that thin bands or those which are intricately covered in gems might not be able to be re-sized. Make sure you check with your jeweler if the ring is re-sizable. Also, if you’re guessing her ring size it’s important to know that rings which have a thick band will need to be larger than her normal rings.
